Lldpdu Transmitted By The Phones - Avaya J100 Series Installing And Administering

Servers, VLAN, and IP configuration
The Avaya J100 Series IP Phones running SIP software support IEEE 802.1AB if the value of the
configuration parameter LLDP_ENABLED is "1" (On) or "2" (Auto). If the value of
LLDP_ENABLED is "0" (off), the transmission and reception of Link Layer Discovery Protocol
(LLDP) is not supported. When the value of LLDP_ENABLED is "2", the transmission of LLDP
frames does not begin until an LLDP frame is received. The first LLDP frame is transmitted within
2 seconds after the first LLDP frame is received. After transmission begins, an LLDPDU is
transmitted every 30 seconds. A delay of up to 30 seconds in phone initialization might occur if the
file server address is delivered by LLDP and not by DHCP.
These phones do not transmit 802.1AB multicast LLDP packets from an Ethernet line interface to
the secondary line interface and vice versa.
By using LLDP, you can configure the following:
• Call server IP address
• File server
• PHY2VLAN
• L2QVLAN and L2Q
• DSCP
• 802.1p priority
